Where & When

Hatching Behavior

There are conflicting accounts of the egg-laying behavior of this genus. Gary LaFontaine writes in Caddisflies that they serenely ride the surface in great numbers to oviposit. In Selective Trout, Swisher and Richards say they dive underwater. Their mention is less detailed and I'm inclined to believe LaFontaine, but perhaps some species exhibits each behavior.

I would like to see a picture of an emerging Chimarra or a pupa stage before emerging if anyone has one. I am baffled and curious to how and when they change from a yellow/orange larva to a black adult fly. Also, what would be a good emerger pattern for this fly? Lafontaine emerger in what color?

Your Thoughts On Chimarra:

Jargon Defined:

Oviposit: To lay eggs.

Pupae: Any insect which spends most of its juvenile lifetime as a larva first becomes a pupa for a time before emerging as a fully grown adult. Depending on the species, the pupal form can be very important for fly fishermen to imitate.
